The vents of the Redoutable are under the casing. The square openings in the casing are limber holes to facilitate draining the superstructure. In submarine technology a vent is a valve fitted to the top of a submarine's ballast tanks to let air escape from the top of the ballast tank and be replaced by water entering through the opening(s) called "flood ports" or "floods" at the bottom of the ...
Subsea valves are used to isolate or control the flow of material through an undersea pipeline (submarine pipeline) or other apparatus.Most commonly used to transport oil and gas, they are designed to function in a sub-marine environment, withstanding the effects of raised external pressure, salt-water corrosion, and bubbles or debris in the material carried.
Submarine escape trunk View inside a submarine escape trunk, looking up from below the lower hatch. An escape trunk is a small compartment on a submarine which provides a means for crew to escape from a downed submarine; it operates on a principle similar to an airlock, in that it allows the transfer of persons or objects between two areas of different pressure.
This Kingston valve, controllable both manually and hydraulically, is known by some as main vent operating gear. Main ballast tanks are in pairs, one on each side of the boat. One Kingston valve serves a pair, but each tank has a vent riser, with air connections and stop valves in the vent riser. The tank bottom is open to the sea through flood ...
The diagram illustrates the operation of a submarine torpedo tube. The diagram is somewhat simplified but does show the working of a submarine torpedo launch. A torpedo tube has a considerable number of interlocks for safety reasons. For example, an interlock prevents the breech door and muzzle door from opening at the same time. The submarine ...
The Kingston valves linking the ballast tanks to the sea could be left open, a practice known as "riding the valves", and the water level in the tanks controlled solely by the vent and blowing air valves. The drawback was that the ballast tanks, open to sea pressure, had a flat surface to the crew compartment and were thus restricted in ...

An Emergency Air Breather (EAB) is a device used on board U.S submarines in emergencies when the internal atmosphere is, or potentially is, unsuitable for breathing. It consists of a mask and air hose. [1] The air hose ends with a fitting that allows quick insertion or removal from air manifolds equipped with quick-disconnect fittings. These ...
